Achilles provides the recognised, integrated route for suppliers to achieve CAS accreditation, maintain continuous compliance, and position themselves for CCS Construction Framework opportunities.
Crown Commercial Service (CCS) is adopting the Common Assessment Standard (CAS) as the recognised industry approach for pre-qualification on the upcoming Construction Works and Associated Services 3 Framework (2026–2034). To support suppliers, CCS has partnered with Achilles to make CAS compliance simple and efficient. Achilles streamlines accreditation and verification, centralises compliance tracking through the MyAchilles platform, and integrates seamlessly with any approved RAB, ensuring that any existing CAS accreditation you hold is recognised.
Achilles centralises your accreditation, updates, and verification so you only submit information once.
Your CAS status remains current throughout the framework, reducing admin, rework, and renewal stress.
A recognised, verified CAS accreditation positions you strongly for CCS Construction Framework bids and wider public-sector work.
GET STARTED
Whether you already hold CAS or are starting from scratch, your next step depends on your current accreditation status. Choose the option that applies to you to stay compliant and ready for the CCS Construction Framework.
You’re all set. Your accreditation is already connected to MyAchilles, and no further action is required unless CCS confirms additional framework needs.
Share your CAS information with Achilles so it can be connected to MyAchilles and made visible to CCS. Use the link provided on this page to authorise the data transfer.
Start your accreditation process with Achilles. Register via Public.Sector@Achilles.com or complete the form to request a call back to begin your CAS assessment.
